International audienceNew hemicryptophane compds. combining a cyclotriveratrylene (CTV) unit, three binaphthol moieties in the linkers and closed by a simple benzene unit have been synthesized enantiomerically and diastereomerically pure. Assignment of their abs. configuration was achieved by chem. correlation. These closed shell host compds. were then tested in the recognition of carbohydrates and compared with their open-shell counterparts. Closing the mol. cage induces a slight drop in affinity, assocd. with an improvement in the stereoselectivity of the recognition process, probably related to the higher preorganization of the cage compds
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
